I know there are a ton of threads on this problem, but none of them seem specific to my problem. I have a problem with the ESP on my 2002 rubicon 500. The dash just flashes. I replaced the shift motor and angle sensor. I preloaded the angle sensor and the problem seemed to have been fixed on first start up. Everything on the dash worked until I tried to shift and it came back. I went through the process again and it played out the same way. I took the shift motor off and tried it and everything worked. The shift motor spun, the dash shifted through the gears, but when I bolted the motor back up it started flashing again. The gear the motor spins doesn't move by hand, just does a back and forth motion. Is there something going on in the transmission? The oil level is good. Curious if anyone has had this problem. Thanks in advance.
